* Speed is how fast something is moving, regardless of direction. It's a scalar quantity, meaning it only has magnitude (a number).

* Velocity is how fast something is moving *and* in what direction. It's a vector quantity, meaning it has both magnitude and direction.

Example:

Imagine two cars:

* Car A is traveling north at 60 mph.

* Car B is traveling south at 60 mph.

Both cars have the same speed (60 mph). However, they have different velocities because they are moving in opposite directions.

In summary:

* Two objects can have the same speed if they are moving at the same rate.

* They will have different velocities if they are moving in different directions.
